Implementation of AES Algorithm on Text And Image using MATLAB

One of the major problems faced by the world today is Data Security. In reality communication channel which is used to transfer data from transmitter to receiver is highly insecure. To resolve this problem the data is being manipulated to another form, so that the person with access to the secret key can only read it. This process of manipulation of original data to another form so that eavesdropper cannot access it, is known as encryption. Advanced Encryption Standard (AES) is the most commonly used algorithm for data encryption. This algorithm can be applied on both text and image. In this paper the input to AES algorithm is Text and an image, which results in encrypted output. This encrypted output is given as an input to AES decryption algorithm, which results in decrypted output. The algorithm is implemented using MATLAB software.
